Managing to fit into two rather large suitcases, Melvin the Machine, from Eindhoven, NL design studio HEYHEYHEY is a portable 38-step Rube Goldberg machine traveling abroad and having a bit of fun along the way. At each stop, if the run is successful, Melvin will finish off with a personalized stamped postcard and affix proper postage before the operator tosses it in the mail. Also on board is an HTC Desire that snaps photos and uploads them to a map so folks can follow along as Melvin travels from place to place. [via The Verge]
